我正在尝试编写测试，以确保我的登录控制器具有某些模型属性并运行某些服务方法

当我运行这个控制器的测试时，我得到一个错误，分别是loginForm和registerForm测试

javax.servlet.ServletException: Circular view path [login]: would dispatch back to the current handler URL [/login] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

及

但是当我运行我的另一个控制器（主控制器）时，我没有得到这些错误

您的

viewsolver

未用于测试。您必须使用当前的

ApplicationContext

，或者在测试中指定

ViewResolver

使用

ApplicationContext

可以将以下内容添加到LoginControllerTest.java中，请注意，我将其更改为使用

SpringJUnit4ClassRunner

运行

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes={TemplateConfig.class})
@WebAppConfiguration

@Autowired
WebApplicationContext wac;

@Before
public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}

或者使用

viewsolver

只需更改

setUp（）

方法即可

@Before
public void setUp() throws Exception {
    mockMvc = MockMvcBuilders.standaloneSetup(controller).build();

    InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
    viewResolver.setPrefix("/WEB-INF/jsp/view/");
    viewResolver.setSuffix(".jsp");

    mockMvc = MockMvcBuilders.standaloneSetup(new LoginController())
            .setViewResolvers(viewResolver)
            .build();
}

欢迎来到堆栈溢出！我想这段代码的95%与您的问题无关。请创建一个演示您的问题的URL。发生这种情况是因为您的映射方法正在返回它们来自的URL。换句话说，他们在呼唤自己。我该如何解决这个问题？代码实际上在运行时有效，只是测试不起作用。第二个答案很好，但第一个答案不行，因为当我为

@RunWith（MockitoJUnitRunner.class）

删除

@RunWith（SpringJUnit4ClassRunner.class）

时，我不断收到断言错误，因为mockito无法运行。
